People conceived through sperm donation have the right to know the father's identity even if the donor wants to remain anonymous, a Victorian parliamentary committee says in a push for world-first legislation.

The Law Reform Committee says the state's laws should be changed to allow donor-conceived people to obtain identifying information about their biological parent.

State legislation currently prohibits people conceived from sperm donations before the Infertility (Medical Procedures) Act came into effect on July 1, 1988, from having access to any identifying information about their donors.

But people conceived using sperm donated after January 1, 1998 have unconditional access to this information.

"While the committee recognises that donors who donated their gametes before 1988 did so on the basis of anonymity, the committee considers that donor-conceived people have a right to know the identity of the person who contributed half to their biological makeup," committee chair Clem Newton-Brown said.

"The committee is convinced that this right must be given precedence, even over the wishes of those donors who would like to remain anonymous."

The committee said donors should not be unreasonably affected by the release of their details and recommended that protections be provided for those who do not wish to be contacted.

Caroline Lorbach, a founding member of the Donor Conception Support Group, said the report achieved the right balance by allowing donor-conceived people to access vital information while giving donors the right to veto unwanted contact.

Ms Lorbach, who has three donor-conceived children, said the recommendations, if legislated, would be a world first.

"If it gets passed through parliament it'll be the first jurisdiction in the world - it's that big and that important," Ms Lorbach told AAP.

"Currently, donor-conceived people who were born in the past are the only people in Australia to be denied the ability to get information about who they are related to, something that most of us take for granted."

Mr Newton-Brown said committee members had initially been in favour of maintaining the status quo.

But submissions received during the inquiry forced them to reconsider, with a unanimous finding that the rights of the child should come first, he said.

"The committee basically changed its view," Mr Newtown-Brown said.

"One by one, we all came to the view unanimously that the right thing to do is to give the rights to the child.

"That outweighs the inconvenience and embarrassment of unwanted approaches."

The committee tabled its report in parliament on Wednesday after a 21-month inquiry into donor-conceived people's access to information about their donors.

The government has six months to respond to the report.
